Description

The present invention relates to a device for deodorizing an odorous component of air with a microbial retention carrier.

In various facilities that generate bad odors, such as composting treatment facilities and wastewater treatment facilities that generate high-concentration bad odors, if the generated bad odors are released into the atmosphere as they are, complaints will be generated from neighboring residents. Therefore, it is indispensable to take measures against odors in order to harmonize with the region. Conventionally, as a device for removing a bad odor, a microorganism holding carrier is housed in a deodorizing tank, air containing a bad odor is sent to the deodorizing tank containing the microbial holding carrier, and the odor is caused by the microorganisms living in the microbial holding carrier. A deodorizing device that decomposes and deodorizes components is known (see, for example, Patent Document 1 and Patent Document 2).

Further, conventionally, a deodorizing device in which this microorganism-retaining carrier is composed of a porous porous material typified by lightweight cellular concrete is known (see, for example, Patent Document 3).

Japanese Unexamined Patent Publication No. 2000-176239 Japanese Unexamined Patent Publication No. 2005-7369 JP 2011-56339

However, since lightweight cellular concrete is very expensive, the invention described in Patent Document 3 has a problem that the price of the apparatus becomes high and it is difficult to spread it widely.

On the other hand, by forming an inexpensive material such as a foam material as a porous porous material, using this porous material as a microbial retention carrier, and constructing a deodorizing device in which the microbial retention carrier is housed in a deodorizing tank, a conventional problem is solved. It is also possible to solve the problem. Here, when dealing with a facility that generates a large amount of malodor, such as a large plant, it is necessary to construct a large deodorizing device equipped with a large deodorizing tank. However, when the deodorizing tank becomes large, a situation in which the air sent into the deodorizing tank passes through only a part of the deodorizing tank tends to occur. Therefore, in the inventions described in Patent Documents 1 to 3, in a large device provided with a large deodorizing tank, the decomposition and deodorization of microorganisms in the microbial retention carrier in the portion through which air does not pass is not sufficiently exhibited, and the deodorizing effect is sufficient. There is a problem that it cannot be exhibited. On the other hand, in the deodorizing device having a configuration in which the air is distributed throughout the deodorizing tank by a stirring device or the like that forcibly agitates the air inside the deodorizing tank, a large fan or a large electric motor for rotating the fan is provided. Since a stirring device is required, there is a problem that the cost of the entire deodorizing device rises.

The present invention has been made in view of such a problem, and even in a large-scale apparatus equipped with a large deodorizing tank, the decomposition and deodorizing function can be fully exhibited while suppressing an increase in manufacturing cost. It is an object of the present invention to provide a microbial deodorizing device capable of producing.

In order to solve such a problem, the invention according to claim 1 includes a hollow deodorizing tank for accommodating a foam material as a microbial retention carrier, blows air into the deodorizing tank, and causes an odor component contained in the air. Is a microbial deodorizing device that decomposes and deodorizes by microorganisms living in the foam material housed in the deodorizing tank, and the deodorizing tank forms an air flow path through which the air passes from one side to the other. In the air flow path, a deodorizing portion filled with the foam material, a ventilation resistance portion provided close to or adjacent to the deodorizing portion to increase the ventilation resistance of the air flowing through the air flow path, and the deodorizing portion. And / or, the chamber portion provided adjacent to or close to the ventilation resistance portion as a room for temporarily storing the air sent into the deodorizing tank, and the air flowing through the air flow path. As a result of the ventilation resistance being increased by the ventilation resistance portion, the air flow is configured to be sent to the deodorizing portion in a state where the air is spread over substantially the entire surface of the deodorizing portion in the chamber portion. And.

In the invention according to claim 2, in addition to the configuration according to claim 1, the ventilation resistance portion is arranged so as to face the air flow direction in the air flow path, and is substantially the entire surface of the air flow path. It is characterized in that it is formed as a ventilation resistance layer that closes the air.

In the invention according to claim 3, in addition to the configuration according to claim 2, the ventilation resistance portion is projected inward from the wall surface of the inner peripheral portion of the deodorizing tank in addition to the ventilation resistance layer. It is characterized by having a ventilation resistance protrusion.

In the invention according to claim 4, in addition to the configuration according to any one of claims 1 to 3, the chamber portion is provided below the deodorizing portion in the deodorizing tank, and the air flow path is described above. It is configured so that the air flows from the lower side to the upper side of the deodorizing tank, and the chamber portion is provided with an introduction portion for introducing the air into the chamber portion, and the air flowing in from the introduction portion is introduced in the horizontal direction. It is characterized in that a diffusion path is formed as an air flow path for diffusion.

The invention according to claim 5 is characterized in that, in addition to the configuration according to claim 4, the diffusion path is formed by a plurality of U-shaped grooves.

The invention according to claim 6 has a substantially mesh-like fall prevention member on the upper side of the chamber portion to prevent the foam material from falling into the chamber portion, in addition to the configuration according to claim 4 or 5. Is characterized by being provided.

The invention according to claim 7 includes, in addition to the configuration according to any one of claims 1 to 6, a sprinkling pipe for conducting water for sprinkling water on the foam material, and below the deodorizing tank. Is provided with a water storage tank for storing the sprinkled water, and the water sprinkling pipe is arranged along the deodorizing tank so that the water stored in the water storage tank can be circulated and sprinkled. It is characterized in that it is arranged.

According to the invention of claim 1, the deodorizing tank provided adjacent to or close to the ventilation resistance portion, the deodorizing portion, and / or the ventilation resistance portion for increasing the ventilation resistance of the air flowing through the air flow path. It has a chamber part as a room to temporarily store the sent air, and as a result of the air flow through the air flow path being enhanced by the ventilation resistance part, the air is an abbreviation for the deodorizing part in the chamber part. Since it is configured to be sent to the deodorizing section in a state of being spread over the entire surface, the air sent to the deodorizing tank is sent to the deodorizing section in a state of being diffused to almost the entire chamber section, and the deodorizing section. Odorous air easily comes into contact with the microbial retention carrier in the entire area. Therefore, even if the air in the deodorizing tank is not forcibly agitated by an air agitator or the like, the odor is decomposed and deodorized by the microorganisms in the entire deodorized portion, and highly efficient deodorization can be performed. As a result, even in a large-scale device equipped with a large-scale deodorizing tank, the decomposition and deodorizing function can be fully exhibited while suppressing a rise in manufacturing cost.

According to the invention of claim 2, the ventilation resistance portion is arranged so as to face the air flow direction in the air flow path and is formed as a ventilation resistance layer that closes substantially the entire surface of the air flow path. As a result of obstructing the easy flow of air over the entire air flow path, the odorous air sent to the deodorizing tank is easily distributed throughout the deodorizing section, and the flow velocity of the air flowing through the deodorizing tank is suppressed to deodorize. The odorous air can be brought into contact with the microbial retention carrier in the entire region for a long time. Therefore, even in a large-scale device equipped with a large deodorizing tank, it is possible to efficiently decompose and deodorize the odor by microorganisms in the entire deodorizing portion, and to exert a higher decomposition and deodorizing function.

According to the third aspect of the present invention, the ventilation resistance portion includes, in addition to the ventilation resistance layer, a shielding protrusion protruding inward from the wall surface of the inner peripheral portion of the deodorizing tank, thereby providing air. The function of suppressing the flow of air near the wall surface inside the deodorizing tank, which is easy to flow, has been further enhanced, and as a result, the odorous air sent into the deodorizing tank stays inside the deodorizing tank and spreads further throughout the deodorizing tank. It will be easier. As a result, even a large-scale device equipped with a large-scale deodorizing tank can exhibit a higher decomposition deodorizing function while suppressing an increase in manufacturing cost.

According to the invention of claim 4, the chamber portion is provided below the deodorizing portion in the deodorizing tank, and the air flow path is configured to allow air to flow from the lower side to the upper side of the deodorizing tank. An introduction section for introducing air is provided in the chamber section, and a diffusion path is formed as an air flow path for horizontally diffusing the air flowing in from the introduction section, so that the air sent from the introduction section can be introduced. , Can be diffused horizontally in the chamber portion and sent to the deodorizing portion. This makes it easier for the odorous air to spread throughout the deodorizing tank. As a result, even a large-scale device provided with a large-sized deodorizing tank 1 can exhibit a higher decomposition deodorizing function while suppressing an increase in manufacturing cost.

According to the invention of claim 5, since the diffusion path is formed by a plurality of U-shaped grooves, the diffusion path is constructed at low cost, and the air sent from the introduction portion is sent to the chamber portion. A structure that diffuses in the horizontal direction can be easily constructed.

According to the invention of claim 6, a substantially mesh-shaped fall prevention member for preventing the foam material from falling into the chamber portion is provided on the upper side of the chamber portion, so that the foam material is formed in the chamber portion. With a simple structure, it is possible to reliably prevent the situation where the air with odor does not reach the deodorizing tank due to falling into the chamber and blocking the air flow path in the chamber.

According to the invention of claim 7, a water storage tank for storing sprinkled water is provided below the deodorizing tank, and the sprinkled water can be circulated and used in the deodorizing portion. Further, since the watering pipe is arranged along the deodorizing tank, the watering pipe for conducting the water to be sprinkled is naturally warmed by the heat generated by the microorganisms in the deodorizing tank. Therefore, even when the microbial deodorizing device is used in a cold region, freezing of water conducting through the watering pipe can be easily and surely suppressed.

[Embodiment 1 of the invention]
Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4.

[Installation mode of microbial deodorizer]
As shown in FIG. 1, the microbial deodorizing device 1A of the first embodiment is installed in a state of being connected to various facilities 100 by an exhaust pipe 200.

The various facilities 100 are devices, facilities, equipment, and the like that generate air containing a foul odor. Specifically, for example, the various facilities 100 are a composting treatment facility, a wastewater treatment facility, etc. that generate a high concentration of malodor, but any other facility that generates air containing a malodor. It may be one. The various facilities 100 are assumed to be large facilities and devices that discharge a large amount of air with a foul odor, but are not limited to this, and may be small facilities and devices.

The exhaust pipe 200 is a pipe, tube, hose, or the like that is made of a material having pressure resistance and corrosion resistance, for example, a material such as metal or vinyl chloride, and allows air to pass through the inside. In the middle of the exhaust pipe 200, a blower 300 for forcibly blowing air from the various facilities 100 side to the microbial deodorizing device 1A side and a valve 400 for opening and closing the exhaust pipe 200 are provided.

[Configuration of microbial deodorizer]
The microbial deodorizing device 1A shown in FIGS. 1 to 4 is formed as a large device, for example, a substantially rectangular parallelepiped device having a size of about 10 meters in length and width and about 3 meters in height. However, the size and shape of the microbial deodorizing device 1A may be any as long as it can deodorize air by holding the foam material 17 (described later) as a "microorganism retaining carrier" inside.

As shown in FIGS. 3 and 4, it is conceivable that the microbial deodorizing device 1A is housed in a box-shaped housing part 500 and used. The accommodating portion 500 accommodates an electric motor, an electric cable, various wirings, various pipes, and the like for driving the microbial deodorizing device 1A.

The microbial deodorizing device 1A of the first embodiment shown in FIG. 1 includes a substantially rectangular parallelepiped deodorizing tank 1. The deodorizing tank 1 can hold a foam material 17 (described later) or the like inside, and is formed of a material having high pressure resistance and corrosion resistance, for example, metal, hard resin, reinforced concrete, or the like.

As shown in FIG. 1, the deodorizing tank 1 is provided with a water storage tank 2, a chamber portion 3, a ventilation resistance layer 4 as a "ventilation resistance portion", and a deodorizing portion 5 in this order from the bottom.

The water storage tank 2 is formed in a container shape with a closed circumference. Inside the water storage tank 2, water for sprinkling water on the foam material 17 (described later) is stored. A pipe insertion hole 6 is partially formed in the water storage tank 2, and a water sprinkling pipe 7 for conducting the water stored in the water storage tank 2 is inserted into the pipe insertion hole 6 (water sprinkling pipe). Details of 7 will be described later).

A micro-bubble generator 8 is provided inside the water storage tank 2. The micro-bubble generator 8 has a function of generating fine bubbles in the water inside the water storage tank 2.

The chamber portion 3 is formed as a hollow chamber on the upper side of the water storage tank 2 via the partition wall 9, and has a function of temporarily storing the air sent to the deodorizing tank 1.

As shown in FIG. 3, a part of the chamber portion 3 is formed through an insertion hole 10 as an “introduction portion” for introducing air into the chamber portion 3, and the insertion hole 10 is formed with an odor in the chamber portion 3. An exhaust pipe 200 for inflowing the contained air is inserted.
Further, as shown in FIG. 3, a plurality of U-shaped grooves 11 formed of a material having high rigidity and corrosion resistance such as concrete or hard resin are arranged inside the chamber portion 3 to provide a flow passage 12. Is forming. The flow passage 12 constitutes a diffusion path 13 that diffuses the air flowing from the exhaust pipe 200 into the chamber portion 3 in the horizontal direction (planar direction in FIG. 3) near the exhaust pipe 200.

Specifically, for example, as shown in FIG. 3, in the diffusion path 13, the openings 11e and 11e of the first row U-shaped grooves 11a and 11a and the openings 11e and 11e of the second row U-shaped grooves 11b and 11b Are arranged in a state of being displaced in the horizontal direction (in a state of being displaced in the vertical direction in FIG. 3). Similarly, the openings 11e and 11e of the second row U-shaped grooves 11b and 11b, the openings 11e and 11e of the third row U-shaped grooves 11c and 11c, and the openings of the third row U-shaped grooves 11c and 11c. Both the 11e and 11e and the openings 11e and 11e of the fourth row U-shaped grooves 11d and 11d are arranged so as to be displaced in the horizontal direction. As a result, the air conducting through the diffusion path 13 flows as shown by the arrow in FIG. 3, and thus flows inside the chamber portion 3 while diffusing in the horizontal direction. However, the arrangement of the U-shaped groove 11 in the diffusion path 13 may be other than that shown in FIG. Further, the diffusion path 13 may be made of a material other than the U-shaped groove 11.

As shown in FIG. 2, a partition wall 3a is provided on the upper side of the chamber portion 3. A ventilation hole portion 3b is formed in the partition wall 3a. An installation protrusion 14 is projected inward from the inner wall of the deodorizing tank 1 above the partition wall 3a, and as shown in FIG. 4, a pallet 15 is arranged above the installation protrusion 14. The pallet 15 is provided with a plurality of square-shaped gaps 15a through which air flows, which are made of a material having high rigidity and corrosion resistance, for example, a hard resin or the like.

As shown in FIG. 4, a fall prevention member 16 is laid on the upper side of the pallet 15. The fall prevention member 16 is formed in a substantially mesh shape by a material having flexibility and high corrosion resistance, for example, a soft resin or the like. The size of the mesh of the fall prevention member 16 is formed to a size such that most of the foam 17 can be held so as not to fall into the chamber portion 3 while allowing air to flow, for example, a diameter of about 2 mm. However, the mesh of the fall prevention member 16 may have any size as long as most of the foam materials 17 do not fall into the chamber portion 3. Note that FIG. 4 shows a state in which the fall prevention member 16 is arranged on the upper side of only a part of the pallet 15 for simplification of illustration, but the fall prevention member 16 is actually on the upper side of the pallet 15. Cover the entire area.

By disposing the pallet 15 and the fall prevention member 16, the foam material 17 falls into the chamber portion 3 while allowing the air flowing into the chamber portion 3 from the exhaust pipe 200 to flow to the upper ventilation resistance layer 4 and the deodorizing portion 5. It can be prevented from doing so.

A ventilation resistance layer 4 is arranged above the pallet 15 and the fall prevention member 16. The ventilation resistance layer 4 is made of a material having a higher ventilation resistance than the deodorizing portion 5 in which the foam material 17 is arranged, for example, rock wool 4a, having a predetermined thickness (for example, several centimeters to several centimeters) over substantially the entire horizontal direction. It is formed as a layer having a thickness of about 10 cm) that covers substantially the entire surface of the deodorizing portion 5 when viewed from the chamber portion 3 side.

The ventilation resistance layer 4 may be made of any material or substance other than the rock wool 4a as long as it is made of a material or substance having high ventilation resistance (for example, a non-woven fabric or a non-woven fabric-like substance). Further, in the first embodiment, the ventilation resistance layer 4 is arranged in substantially the entire horizontal direction, but if the ventilation resistance is high and the flow velocity of the air flowing into the deodorizing portion 5 can be reduced, any position can be used. It may be arranged in any shape. For example, the ventilation resistance layer 4 may be arranged only in a part in the horizontal direction, for example, only the substantially central portion in the plan view, only the peripheral portion in the plan view, or only the side where the exhaust pipe 200 is arranged in the plan view. The ventilation resistance layer 4 may be provided on the upper side of the deodorizing portion 5.

As shown in FIGS. 1 and 2, in the first embodiment, the ventilation resistance layer 4 is configured in a state in which the rock wool 4a and the foam material 17 constituting the deodorizing portion 5 are mixed. This is to prevent the ventilation resistance layer 4 formed of only the rock cotton 4a from aging and the ventilation resistance from becoming too large. However, the ventilation resistance layer 4 may be configured so that the foam material 17 is not mixed.

As shown in FIGS. 1 and 2, a deodorizing portion 5 is provided above the ventilation resistance layer 4 in contact with the ventilation resistance layer 4. The deodorizing portion 5 is filled with a large number of foaming materials 17 and is formed in a layer having a predetermined thickness (for example, a thickness of about 1 meter to 3 meters, but may be thicker or thinner than this). .. Although FIGS. 1 and 2 show the foaming material 17 only in a part of the deodorizing portion 5 for the sake of simplification of the description, the foaming material 17 is actually filled in substantially the entire area of the deodorizing portion 5.

The individual foaming material 17 constituting the deodorizing portion 5 is, for example, a porous porous material having a diameter of about 5 mm to several tens of millimeters. The diameter of each hole (not shown) of the foam material 17 is about several micrometers to about several tens of micrometers. In the individual pores (not shown) of the foam material 17, microorganisms having a deodorizing effect (for example, microorganisms that biodegrade chemical substances that cause bad odors (for example, ammonia and hydrogen sulfide) (for example, nitrifying that decomposes ammonia) are formed. Many bacteria, nitrifying bacteria, sulfur bacteria that decompose hydrogen sulfide, etc.) can inhabit.

The foam material 17 of this embodiment is formed, for example, by firing recycled glass using a glass bottle as a main raw material to foam it so that the surface area per gram is about 80 square meters. As a result, it is possible to form the foaming material 17 which can obtain a high deodorizing effect by inhabiting a large amount of microorganisms in a small volume at low cost. Further, the foam material 17 has a structure having low ventilation resistance. As a result, it is possible to prevent the blower 300 from becoming excessive in air resistance, and to reduce the electricity bill for driving the blower 300.

As described above, the foam material 17 of this embodiment is formed by firing recycled glass. By constructing the foam material 17 in this way, there is a possibility that aging deterioration will occur due to corrosiveness to gases such as ammonia and hydrogen sulfide, as in the case where the foam material is formed of concrete (see [Patent Document 3] above). It is possible to suppress the possibility of aging deterioration due to microbial decomposition, such as when the foam material is formed of an organic substance such as wood chips.

The foam material 17 is preferably formed of a material having a low price and a large surface area, but any member (for example, wood, ceramic, etc.) can be used as long as it functions as the foam material 17. It may be formed.

Located in the deodorizing portion 5, a ventilation resistance protrusion 18 as a "ventilation resistance portion" is projected on the inner wall of the deodorization tank 1. The ventilation resistance protrusion 18 is provided in substantially the entire inner wall of the deodorizing tank 1 where the flow rate of air tends to increase inside the deodorizing tank 1. However, the ventilation resistance protrusion 18 may be provided at any position and in any manner as long as it reduces the flow velocity of the air flowing through the deodorizing tank 1 from below to above. For example, the ventilation resistance protrusion 18 may be provided only in the vicinity of the position where the exhaust pipe 200 is provided in a plan view.

An opening 19 is formed above the deodorizing portion 5 of the deodorizing tank 1. The inside of the deodorizing tank 1 forms an air flow path 20 through which air passes from the lower side (chamber portion 3) as the "one side" to the upper side (opening 19) as the "other side". That is, in the air flow path 20 inside the deodorizing tank 1, air passes from the lower side to the upper side as shown by an arrow in FIG. However, the "one side" and the "other side" of the air flow path 20 may be in any position. For example, "one side" may be above the deodorizing tank 1 and "the other side" may be below the deodorizing tank 1, "one side" may be one side surface of the deodorizing tank 1, and "the other side" may be deodorizing. It may be the other side of the tank 1.

Further, the deodorizing tank 1 of the first embodiment is provided with a watering pipe 7. The watering pipe 7 is arranged along the wall surface of the deodorizing tank 1, particularly along the deodorizing portion 5 of the deodorizing tank 1.

One end side of the watering pipe 7 is arranged in the water storage tank 2, and the other end side is arranged above the deodorizing tank 1. Further, as shown in FIGS. 1 and 2, a pump 21 is provided in a part of the watering pipe 7. The pump 21 is driven by an electric motor (not shown), sucks the water stored inside the water storage tank 2 into the water sprinkling pipe 7, and has a function of flowing the water from the bottom to the top of the water sprinkling pipe 7. A water sprinkling portion 22 is provided on the other end side of the water sprinkling pipe 7. The sprinkler portion 22 is formed as a sprayer, and the water conducted through the sprinkler pipe 7 is atomized from above the deodorizing portion 5 and dropped onto the deodorizing portion 5. However, the sprinkler portion 22 may have any configuration as long as water can be dropped onto the deodorizing portion 5. For example, the sprinkler portion 22 may be formed as one or a plurality of small holes opened in the sprinkler pipe 7. You may.

Further, the watering pipe 7 is provided with a net-like strainer 23. The strainer 23 functions to filter, remove, and recover the fine foaming material 17 that flows together with the water inside the watering pipe 7.

[Usage of microbial deodorizer]
Next, the usage mode of the microbial deodorizing device 1A of the first embodiment will be described.

In the first embodiment, when the valve 400 is opened, the air containing the malodor generated in the various facilities 100 is sent to the chamber portion 3 of the microbial deodorizing device 1A through the exhaust pipe 200 by the air blown by the blower 300. A ventilation resistance layer 4 exists on the upper side of the chamber portion 3 via a partition wall 3a in which a ventilation hole portion 3b is formed as an opening, and the air flowing into the chamber portion 3 is immediately caused by the height of the ventilation resistance of the ventilation resistance layer 4. Since the flow to the upper side is hindered, the air flowing into the chamber portion 3 passes through the flow passage 12 of the U-shaped groove 11 including the diffusion path 13 and diffuses in the chamber portion 3 in the horizontal direction.

Then, the air diffused over the entire chamber portion 3 passes through the ventilation hole portion 3b and flows upward. At this time, since the ventilation resistance of the ventilation resistance layer 4 is high, the flow of air is suppressed in the ventilation resistance layer 4, and the flow speed of air upward becomes slow. As a result, the air slowly flows upward, passes through the ventilation resistance layer 4 and reaches the deodorizing section 5, and then slowly flows upward in the deodorizing section 5. Therefore, the staying time of the air in the deodorizing portion 5 becomes long, and a high deodorizing effect is produced.

When the air that has reached the deodorizing portion 5 comes into contact with the foam material 17, the malodorous component contained in the air is fixed inside the foam material 17 and decomposed by the inhabiting microorganisms, and the malodorous component is removed. Here, the air that has flowed into the chamber portion 3 from the exhaust pipe 200 diffuses over substantially the entire horizontal direction in the chamber portion 3 and flows upward to reach the deodorizing portion 5, so that the air is substantially horizontal in the deodorizing portion 5. It comes into contact with the foam material 17 over the entire area. That is, in the deodorizing section 5, air comes into contact with many foaming materials 17 and can exert a high deodorizing effect.

Further, in the deodorizing section 5, the ventilation resistance protrusion 18 inhibits the flow of air in substantially the entire inner wall of the deodorizing tank 1 through which air easily flows, so that the flow velocity of air becomes faster near the inner wall of the deodorizing tank 1 to deodorize. Suppress the situation where the effect is reduced. As a result, air can be slowly flowed in substantially the entire area of the deodorizing portion 5, and a high deodorizing effect can be achieved.

Then, the air that has passed through the deodorizing portion 5 and whose malodorous components are decomposed and deodorized by the microorganisms of the foaming material 17 is discharged to the outside from the opening 19 above the deodorizing tank 1. In this way, the microbial deodorizing device 1A of the first embodiment removes the malodorous component of the air containing the malodor and releases the deodorized air to the outside.

On the other hand, in the microbial deodorizing device 1A of the first embodiment, the micro-bubble generator 8 generates fine bubbles in the water inside the water storage tank 2, and the water containing the bubbles flows into the watering pipe 7.

The water flowing into the water sprinkling pipe 7 flows from the lower side to the upper side, and is sprinkled from the upper water sprinkling portion 22 into the deodorizing tank 1. The sprinkled water is dropped into the deodorizing tank 1 and used for the growth of microorganisms inhabiting the deodorizing portion 5 and the foam material 17 of the ventilation resistance layer 4. The water sprinkled inside the deodorizing tank 1 is water having a high air content, including fine bubbles generated by the microbubble generator 8 inside the water storage tank 2, and therefore the inside of the foam material 17 and the water storage. It is possible to promote the growth and activity of microorganisms that live in the water stored in the tank 2.

Further, the water further dropped from the deodorizing section 5 and the ventilation resistance layer 4 is dropped into the chamber section 3, further dropped from the chamber section 3 into the water storage tank 2, and stored again in the water storage tank 2. In this way, in the microbial deodorizing device 1A, water is circulated and used. It is desirable that the amount of water sprinkled from the sprinkling unit 22 into the deodorizing tank 1 and the frequency of sprinkling water be changed according to the temperature and the like in order to grow the microorganisms that settle on the foam material 17 and inhabit. For example, in summer when the temperature is high, it is desirable to increase the number of times of watering from the watering unit 22 to the inside of the deodorizing tank 1 and the amount of water sprayed each time.

Here, since the microorganisms living in the foam material 17 generate heat during activity, the deodorizing portion 5 and the ventilation resistance layer 4 in which the foam material 17 is arranged are in a heat-generating state. Since the water sprinkling pipe 7 is arranged along the wall surface of the deodorizing tank 1, the water flowing inside the water sprinkling pipe 7 is warmed by the heat generated from the deodorizing portion 5 and the ventilation resistance layer 4. Therefore, even when the microbial deodorizing device 1A is used in a cold region, freezing of water conducting inside the watering pipe 7 can be suppressed.

Further, the fine foam material 17 existing in the deodorizing portion 5 and the ventilation resistance layer 4 falls into the water storage tank 2 together with the dropping of water and precipitates in the water storage tank 2. The fine foam material 17 settled in the water storage tank 2 is filtered by a strainer 23 provided in the watering pipe 7 to be removed and recovered.

[Action effect]
As described above, in the first embodiment, the ventilation resistance layer 4 for increasing the ventilation resistance of the air flowing through the air flow path 20 and the deodorizing portion 5 and / or the ventilation resistance layer 4 are provided adjacent to or close to each other. It is provided with a chamber portion 3 as a chamber for temporarily storing the air sent to the deodorizing tank 1, and the air flow through the air flow path 20 is enhanced by the ventilation resistance layer 4, and as a result, the air is released. Since the chamber portion 3 is configured to be sent to the deodorizing portion 5 in a state of being spread corresponding to substantially the entire surface of the deodorizing portion 5, the air sent to the deodorizing tank 1 is diffused to substantially the entire chamber portion 3. In this state, the air is sent to the deodorizing section 5, and the air with an odor easily comes into contact with the foam material 17 in the entire deodorizing section 5. Therefore, even if the air in the deodorizing tank 1 is not forcibly agitated by an air agitator or the like, the odor is decomposed and deodorized by the microorganisms in the entire deodorizing portion 5, and highly efficient deodorization can be performed. As a result, even in a large-scale device provided with a large-scale deodorizing tank 1, it is possible to fully exert the decomposition and deodorizing function while suppressing an increase in manufacturing cost.

In the first embodiment, the ventilation resistance layer 4 is arranged so as to face the air flow direction in the air flow path 20 and is formed as a ventilation resistance layer that closes substantially the entire surface of the air flow path 20. As a result of hindering the easy flow of air over the entire air flow path, the odorous air sent to the deodorizing tank 1 is easily distributed over the entire deodorizing section 5, and the flow velocity of the air flowing through the deodorizing tank 1 is suppressed. Therefore, the foam material 17 in the entire deodorizing portion 5 can be brought into contact with odorous air for a long time. Therefore, even in a large-scale device provided with a large deodorizing tank 1, it is possible to efficiently decompose and deodorize the odor by microorganisms in the entire deodorizing section 5.

In the first embodiment, by forming the ventilation resistance layer 4 with a non-woven fabric-like material, dust mixed with a foul odor flows into the deodorizing portion 5, and the foam material 17 disposed in the deodorizing portion 5 It is also possible to prevent the pores from being blocked.

In the first embodiment, in addition to the ventilation resistance layer 4, the ventilation resistance protrusion 18 projecting inward from the wall surface of the inner peripheral portion of the deodorizing tank 1 is provided, so that air can easily flow. The function of suppressing the flow of air near the wall surface inside the deodorizing tank 1 is further enhanced, and as a result, the odorous air sent into the deodorizing tank 1 stays inside the deodorizing tank 1 and spreads further throughout the deodorizing tank 1. It will be easier. As a result, even a large-scale device provided with a large-sized deodorizing tank 1 can exhibit a higher decomposition deodorizing function while suppressing an increase in manufacturing cost.

In the first embodiment, the chamber portion 3 is provided below the deodorizing portion 5 in the deodorizing tank 1, and the air flow path 20 is configured to allow air to flow from the lower side to the upper side of the deodorizing tank 1. Is provided with an insertion hole 10 for introducing air into the chamber portion 3, and a diffusion path 13 as a flow passage 12 for diffusing the air flowing in from the insertion hole 10 in the horizontal direction is formed. The air sent from the hole 10 can be diffused horizontally in the chamber portion 3 and sent to the deodorizing portion 5. As a result, the odorous air can be more easily distributed over the entire deodorizing tank 1. As a result, even a large-scale device provided with a large-sized deodorizing tank 1 can exhibit a higher decomposition deodorizing function while suppressing an increase in manufacturing cost.

In the first embodiment, since the diffusion path 13 is formed by a plurality of U-shaped grooves 11, the diffusion path 13 is constructed at low cost, and the air sent from the insertion hole 10 is taken into the chamber portion. In 3, a structure that diffuses in the horizontal direction can be easily constructed.

In this embodiment, the foam material 17 is provided in the chamber portion by providing a substantially mesh-shaped fall prevention member 16 on the upper side of the chamber portion 3 to prevent the foam material 17 from falling into the chamber portion 3. With a simple structure, it is possible to reliably prevent a situation in which air with an odor does not reach the deodorizing tank 1 due to falling into 3 and blocking the air flow path 20 in the chamber portion 3.

In the first embodiment, a water storage tank 2 for storing the sprinkled water is provided below the deodorizing tank 1, and the sprinkled water can be circulated and used in the deodorizing section 5. Further, since the watering pipe 7 is arranged along the deodorizing tank 1, the watering pipe 7 for conducting the water to be sprinkled is naturally warmed by the heat generated by the microorganisms in the deodorizing tank 1. Therefore, even when the microbial deodorizing device 1A is used in a cold region, freezing of water conducting through the watering pipe 7 can be easily and surely suppressed.

The upper protrusions 25b and the upper protrusions 25b are alternately arranged in the horizontal direction. As shown in FIG. 6, in the third embodiment, the lower protrusion 25a is projected upward from the partition wall 3a. Further, a plate-shaped ceiling portion 19a is provided from one side above the deodorizing tank 1 to the other side, and the opening 19 is formed on the other side of the deodorizing tank 1 with respect to the ceiling portion 19a.

In the third embodiment, instead of the sprinkling portion 22 of the first embodiment, a plurality of, for example, five sprinkling portions 22a, 22b, 22c, 22d, for each gap between the lower protrusion 25a and the upper protrusion 25b, 22e is provided. However, the number of sprinkling portions 22a, 22b, 22c, 22d, 22e does not necessarily match the number of gaps between the lower protrusion 25a and the upper protrusion 25b, and is arranged in the deodorizing portion 5 and the ventilation resistance layer 4. What is the arrangement position and the number of arrangements of the watering portions 22a, 22b, 22c, 22d, and 22e as long as sufficient positions and numbers are provided for inhabiting the microorganisms of the foaming material 17? It may be.

The configuration of the microbial deodorizing device 1C other than the above is the same as that of the microbial deodorizing device 1A of the first embodiment.

In the third embodiment, the air flowing into the ventilation resistance layer 4 and the deodorizing portion 5 from the ventilation hole portion 3b through the chamber portion 3 is a path shown by an arrow in FIG. 6 along the formed air flow path 20. It flows through the ventilation resistance layer 4 and the deodorizing portion 5 along the above. Specifically, the air that has flowed into the ventilation resistance layer 4 and the deodorizing portion 5 from the ventilation hole portion 3b changes its course from bottom to top and from top to bottom in the vertical direction from one side to the other side (FIG. Proceeds from the right side to the left side in 6) and is discharged to the outside through the opening 19.

In the microbial deodorizing device 1C of the third embodiment, the air flow path 20 of the ventilation resistance layer 4 and the deodorizing portion 5 is labyrinth-shaped by the lower protrusion 25a and the upper protrusion 25b, and the partition wall 3a and the ceiling portion 19a. As compared with the configuration in which the lower protrusion 25a and the upper protrusion 25b, and the partition wall 3a and the ceiling portion 19a are not provided as in the first embodiment, the ventilation resistance layer 4 and the deodorizing portion 5 are formed. The distance traveled by air increases. Therefore, in the ventilation resistance layer 4 and the deodorizing portion 5, the amount of air in contact with the foam material 17 (and the microorganisms inhabiting the foam material 17) increases. Therefore, a higher deodorizing effect can be obtained in the ventilation resistance layer 4 and the deodorizing portion 5.

Water can be sprinkled on the foam material 17 of the deodorizing portion 5 and the ventilation resistance layer 4 without being hindered by the lower protrusion 25a and the upper protrusion 25b, and the growth of microorganisms in the foam material 17 can be maintained. In the third embodiment, the lower protrusion 25a is projected upward from the partition wall 3a below the ventilation resistance layer 4, and the air flow path 20 of the ventilation resistance layer 4 and the deodorizing portion 5 has a labyrinth shape. Not limited to this, for example, the lower protrusion 25a is projected from the side wall surface of the deodorizing tank 1 at the position of the deodorizing portion 5, and only the air flow path 20 of the deodorizing portion 5 has a labyrinth shape. You can also do it.
